Meter Amalgamation: Combining Two Electricity Meters Into One

Can you combine two electricity meters into one, and how does meter amalgamation actually work? Yes, and it is a genuine job we complete regularly, usually for a homeowner who has bought two adjoining properties or units and wants one account, or a household consolidating supply so a single solar and battery system can cover the whole roof. It involves a Level 2 ASP altering the consumer mains and switchboard, an application to the network distributor, and coordination with your retailer to close one of the two National Metering Identifiers, and in many cases the old meter position can be kept in place rather than physically removed, in case the property is ever separated again.

1. What meter amalgamation actually involves

Most Sydney properties are set up with one supply point and one meter per title or per unit. Meter amalgamation changes that by physically combining the wiring downstream of two meters so the property runs as a single point of supply, closing one meter and its National Metering Identifier while keeping the other as the property's single account. It is a different job to a straightforward meter upgrade, a meter relocation, or the general changes covered in our electricity meter guide, since those change how or where you are metered, while amalgamation changes how many connection points exist at all.

2. The two most common reasons people ask for this

The requests we get for meter amalgamation tend to fall into two groups. The first is a homeowner or investor who has bought two adjoining properties, or two units within the same strata complex, and simply wants one bill and one account rather than managing two separate connections indefinitely. The second, and increasingly common, is a household installing solar and a home battery who wants generation and storage to cover the whole property through a single point of supply rather than being split awkwardly across two accounts, which can otherwise limit how effectively the system is sized and used.

3. Why solar and battery systems drive so many of these enquiries

When a property has two separate meters, a solar and battery system installed on one side cannot easily share its generation and stored energy with the other side of the property without amalgamation, since each meter is its own point of common coupling with its own export limits. Combining the two into a single supply point means the whole system, panels, inverter and battery, works as one, which is often the actual goal behind a request that starts out sounding like a simple billing question.

4. The reversible option, and why it matters for strata and multi title properties

A genuinely useful option in many amalgamation jobs is keeping the original meter board and wiring physically in place rather than removing it, with the amalgamation done in the wiring downstream of the meters rather than by ripping out the second connection entirely. This matters most for owners of adjoining strata units or subdivided properties who want the benefit of a combined supply now but may want to separate the property again later, whether that is selling one unit separately or a future change in ownership. Leaving the original infrastructure in place, even disconnected, keeps that option open without a second, more disruptive job down the track.

5. What a Level 2 ASP actually does on site

Combining two supply points means altering the consumer mains and switchboard arrangement on at least one side of the property, which is Level 2 accredited work under the NSW Service and Installation Rules rather than standard electrical work. The ASP designs the new single point of supply arrangement, confirms the remaining switchboard can safely carry the combined load, completes the physical wiring changes, and lodges the required notification with the distributor once the work is finished, the same category of paperwork required for any other metering related service alteration.

6. The network and retailer side of the process

Because amalgamation changes the number of connection points on a property, it needs an application to the network distributor, either Ausgrid or Endeavour Energy depending on where the property sits, before work goes ahead. Your electricity retailer is also involved, since the meter being removed from service has its own National Metering Identifier that needs to be formally closed once the physical work is done, otherwise you can be left with a phantom account or billing confusion on a connection point that no longer functions. If you are not sure which distributor covers your address, check your network area in seconds with our postcode checker before starting the application.

7. Typical process and what to expect

A meter amalgamation job generally starts with a site assessment to confirm both supply points, the existing switchboard capacity and what the combined load will look like, followed by the distributor application, the physical Level 2 work itself, testing, and finally the retailer side closure of the redundant meter. Because it touches both the electrical installation and two separate accounts, it typically takes longer end to end than a straightforward switchboard job, though the on site work itself is often completed within a day once approvals are in place.

How High Demand Electrical helps

We handle meter amalgamation regularly for Sydney homeowners consolidating solar and battery systems, and for owners bringing two titles or two strata units under one account, managing the Level 2 electrical work, the distributor application and the coordination with your retailer as one job rather than leaving you to chase separate parties. As one of Sydney's most trusted Level 2 ASPs, we service homes and businesses across Sydney's West, South West and Sutherland Shire, and we will always flag whether keeping your original meter position in place as a reversible option makes sense for your property before anything is physically removed.
